RIFLE-SIGHT.

Specification of Letters Patent.

Patented April 10, 1906.

Application filed July 3, 1905. Serial No. 268,160.

To ail whom it may concern:

Be it known that I, JOHN N. OLsoN, a citizen of the United States, residing at Butte, in the county of Silverb ow and State of Montana, have invented certain new and useful Improvements in Rifle-Sights; and I do declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same This invention relates to rifle-sights.

The object of the invention is to provide a muzzle-sight for rifles, by the use of which accurate aim may be taken at objects located at various distances.

A further object is to provide a sight of this character which will be simple and inexpensive in construction, efficient and reliable in use, and well adapted to the purpose for which it is designed.

With the above and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, aswill be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of a rifle-barrehshowing the application of the invention thereto. Fig. 2 is a perspective view of the sight removed from the barrel. Fig. 3 is a sectional view showing a modified construction of the sight, and Fig. 4 is a perspective view show ing another modified form of the sight.

Referring more particularly to the drawings, 1 denotes the sight, which consists of a substantially triangularly-shaped block the base of which is dovetailed, as shown at 2, to facilitate the application of the same to the end of the rifle-barrel, which is provided with a dovetail groove or recess to receive the dovetailed base of the sight. In the inclined sides of the block are formed a series of V- shaped notches 3, said notches being arranged one above the other to form a series of parallel horizontally-disposed range-graduation surfaces 4, said surfaces being connected across the front face of the sight by means of raduation marks or scores 5, which may be ormed on said front surface of the sight by painting or, as shown in Fig. 3 of the drawings, may be formed of a strip 6 of separate and different material from that of which the sight is composed. This strip 6 is inlaid in the surface of the sight and is preferably of a contrasting color to that of the sight. On the upper end of the sight-block 1 is formed a sight-tip 7, from the base of which a linegraduation mark or strip 8 extends vertically across the center of the front surface of the sight, as shown.

In Fig. 4 of the drawings the sight-block 1 is shown as having its front face formed of a sheet or plate 9 of material separate and different from the material of which the block is formed, said plate 9 being preferably formed of ivory or similar material, on which plate is placed the range and line-graduation marks hereinbefore described.

The sight-block 1 may be used in connection with any suitable form of rear sight, said rear sight being here shown and is preferably formed of a vertical transversely-disposed plate 10, secured to the rifle-barrel near the stock end of the same. Said rear-sight plate 10 is provided with a centrally-disposed notch 12. When taking aim to shoot at point-blank range, the tip 7 of the front si ht is lined with the center of the target or ot er object, and sight is taken across said tip through the notch 12 in the rear sight 10. When aiming to shoot at two-hundred-yards range, the stock of the gun is lowered to bring the upper edge of the rear-sight plate 10 into line with the first or upper graduation-surface 4 of the front sight, the tip of said front sight beginning in line with the center of the target, as described in the first instance, sight being taken in like manner through the notch in the rear sight and across said tip. In like manner the rifle is aimed at three-hundred, four-hundred, and five-hundred yards range by lowering the stock to bring the upper edge of the rear-sight plate into alinement with the next successive graduation-surface of the front si ht, the tip of said front sight being always eld in line with the center of the target. By thus lowering the stock and barrel of the rifle the ball will be given the necessary upward deflection or rise to cause the same to strike the center of the target at the various distances or ranges at which the same may be located, the vertical graduation-mark on the front sight giving the proper line or lateral direction for aiming the rifle.

From the fore oing description, taken in connection with t e accompanying drawings,

the construction and operation of the invention will be readily understood without requiring a more extended eX lanation.

Various changes in the orm, proportion, and the minor details of construction may be resorted to without departing from the prin- IIO ciple or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A rifle-si ht consisting of a triangularlyshaped block aving in its edges a series of oppositely-disposed notches forming graduated, parallel, horizontally-disposed surfaces arranged one above the other, horizontallydisposed, graduated range-marks arranged on the front side of said block in line with and connecting the opposite horizontallydisposed surfaces of said notches and a vertical, centrally-disposed line-mark also arranged on said front surface of the sight, substantially as described.

2. A rifle-si ht consisting of a triangularlyshaped block having'in its edges a series of oppositely-disposed notches forming graduated, parallel, horizontally-disposed surfaces arranged one above the other, horizontallydisposed, graduated range-marks arranged 011 the front side of said block in line with and connecting the opposite horizontally disposed surfaces of said notches and a vertical, centrally-disposed line-mark also arranged on said front surface of the sight, said marks being formed by inlaid strips of material of a contrasting color to that of the sight, substantially as described.

3. A rifle-sight consisting of a triangularlyshaped block having in its edges a series of oppositely-disposed notches forming graduated, parallel, horizontally-disposed surfaces arranged one above the other, a surface-forming layer of material other than that of which the sight is formed secured to and sha ed to conform to the outline of the front ace of said sight, raduated horizontallydisposed range mar s and a central line mark arranged on said surface-forming layer, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
